Behaviorist Theory is a psychological approach that focuses on observable behaviors rather than internal mental processes. It suggests that all behaviors are learned through interactions with the environment, primarily through conditioning. This theory emphasizes the role of reinforcement and punishment in shaping behavior, as proposed by key figures like B.F. Skinner and John B. Watson. In behaviorism, learning occurs through two main types of conditioning: classical conditioning, which involves associating a neutral stimulus with a significant one, and operant conditioning, which involves modifying behavior through rewards or consequences. This theory has been influential in various fields, including education and therapy, by promoting techniques that encourage desired behaviors.
